## Abstract

We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model BAe.125 series 800A (including C- 29A and U-125) airplanes, and Hawker Beechcraft Model Hawker 800XP airplanes. This AD requires doing an inspection to determine the serial number and part number on the main landing gear (MLG) upper casing, and replacing the MLG assembly with a serviceable MLG assembly if necessary. This AD results from a report indicating that the MLG casings have received improper hydrogen embrittlement relief. We are issuing this AD to prevent a fracture of the MLG casings and a collapse of the affected MLG, which could adversely affect the airplane's continued safe flight and landing.
